Summary:
Updating react-devtools plugin to the latest version.
As Flipper doesn't use a websocket anymore, this plugin was not working. In this diff, we are creating a websocket connection parallel to the rSocket connection which is used by the devtools. First we thought about tunneling the websocket through our rSocket, but this would be a lot more work.
By default they create a web-socket running on port 8097. But if this port is in use another port is used. The hostname and port to connect to is sent to the client-plugin.
